Hi there!
Since a couple of days I have problems to use the Orchestrator Client (jnlp file). It throws the error "Unable to launch the application" just after the "verifying" screen. In "Details" I see the message "Missing required Permissions manifest attribute in main jar: https://host:8281/vco/client/lib/o11n-application.jar".
The problem is only for remote computers. If I launch the client from the vCenter Machine (wich has orchestrator installed), then it starts fine.
Its like a java new requirement for jnlp files.
Any ideas?
